Referring more particularly to the drawings there is shown, by way of example, a portion of a vehicle body which is a door 1 having a window opening2; The window opening 2 is closed by the window'pa'nel 3 which is slidable upwardly and downwardly in the windowphannel'g'uideways 4 and 5. It will be noted that the upper portion of the front door pillar 6 has an angular slope. To conform to the angular slope of the pillar 6, the front upright edge 7 of; the panel 21 of the plate 18 and the web portion of felt then woundaround the outer face of the tubular por- 3 likewise has an angular slope, that is, it is inclined relative to the rear upright edge 8 of-the panel 3. opening 2 is defined by the garnish moulding 9. The upper and side edges of the, window, when in raised position, are sealed by the channel strip 10 having the upstanding pile lining l'l which" engages and seals the edge of the panel. The pile lined channel'lfl extends aroundthe sides and top of the'window' opening and serves both as a window guid'way and header strip. The window guide charmer lining 11, as shown, may be mad'e'from'a's'tiff pile vulcanized in rubber base. The channel member 10 is'h'eld in'place between the 'rev'e'al I2 and the garnish moulding.

The bottom edgeof the window is provided with any suitable window'sa'sh channel The window isarrang'ed'to be raised and lowered; by

any suitable window regulator such as thep'lanm graph type shown which 'briefiy lcomprises a stamped gear sector 14 providedwith a lifting arm 15. The sector may be driven by any'wellknown means such as the well-known crank and pinion (not shown). The lifting arm 15 is supplemented by a check link 16 Wh'ichhas'a pivotal connection (not shown) with the regulator support plate 17. In this type of plano'graph' or check link regulator the arms 15 and 16 are pivoted t0 the attachment plate 18 and due'to' their planograph action maintainthe plate 18 hori zonta1 and consequently keep thewindow" from cooking and binding in the guides'' and 5' as it is raised and lowered. V T f The instant invention concerns the attachment between the regulator arid'the window- Threattachment herein takes the form of the plate 18 to which the arms'15 and 16 are pivoted as'at 19a'nd 20, respectively. The uppered ge .of. the plate 18 is rolled back upon itself as at 21 so that the edge 22 of the rolled-ovrportion 21 is spaced from the face of theplate 18 to'formthe gap 23 (Figure 5); The upper face 24 of the rolled back portion 21 is preferably, although not necessarily, formed so that section it isa semi-circle having its center at 25. The lower face' 26 ofthe rolled-over portion 21 in section islikewise preferably a semi-circle having its center. as at '27. The rolled-over edge 21 in'a' sense'forms a somewhat flattened elongatedtube having a lengthwiseslot23and its axis extending'pa'rallel to the lowr'fedge'of the window panel 3. It will' be r rote'd (Figure 5) that the vertical or up -and'do'wn diameter of the rolled-over portion 21 is longer than the horizontal or transverse diameter- 'for reasons which will be explained below.

Inas'muchas the tubular portion 21 of the plate 18'isar'ranged. to travel back and forth 'in' the track'28 as the window is raised and lowered, and inasmuch as'it is desirable to "prevent rattles be tween the track and the attaching plate andlto reduce the friction between thesetwo members, to this end a suitable surface of friction reducing plate 18.

The inside periphery of the window" and noise preventing material is preferably interposed between the rolled-over edge 21 and the track 28. Preferably this material comprises a layer of felt 33 impregnated with lubricant secured to the outer surface of the plate 18. To secure the felt 33 to the plate 18, one of the edges of thefelt is folded around a cord and stitched as at 3% to form a pleat extending lengthwise of the sheet of" felt. 'The diameter of this pleat is somewhat greater than the gap 23 between the rolled-over edge 21 and the adjacent face of the Hence, the pleat is slid lengthwise through the hollow inside of the tubular portion tion 21'. The plate 18 is provided with the transverse groove 35. Suitable tooth shaped lugs 38 are struck perpendicularly from the plate 18 adjacent the V-groove 35 before the felt is assembled thereto, as shown in the dotted lines. After the pleat has b ee n inserted in the rolled-over portion 21, as above described, and the felt wrapped over the rolled-over portion, the free edge j'of the web portion of the felt is impaled upon the pointed lugs 58 and inserted in the V-gro ove35. A V Shaped felt retainer 37 is then inserted in thegroove over the free edge'of'the felt and the pointed lugs 28 and round lugs 51 bent over into engagement with the outer'e'dge of the felt retamersrthes' securely clamping the felt between the retainer andthe v groo ve.

Since, obviously, if: the window is raised and lowered the attachment plate 18 must travel back forth. along the, lower edge of the window and since it is an obje'ctof the invention to make the windowfreelyrotatable in and out of the window opening"about'its regulator support, to this end the sash'channel 13 has spot welded or otherwise suitably fixed thereto a track'28. The track 28 roughly comprises an'upper lip 29 which is flat and securedito the sash channel 13 and a lower 11530 which is preferably curved about a true radius and cooperates with lip 29' to form'a socket forthe 'roll ed-over edge 21of plate 18. It will 'be" noted that th edge 31 of the lip 30 is spaced from the flat upper lip 29 to produce the 51m; 32. [This slot 32, that is, the distance'between the 'edge31 of the lip 30 and the lip 29, is greater than 'the short or transverse diameter of the rolled-over portion 21 of the plate 18, but this slot'ior distance is somewhat less than the overall long diameter of the portion 21 in conjunction with its felt covering 33. Hence, 'as shown 'in Figure 3,.the window is free 'to' rotate in and out within limits without the plate 18 be coming detached frorn the track 28, but if the win dow is tilted inwardly the garnish. moulding. and channel guide .firstbeihg removed) asufficient distancefthe'track 28' rotates about the rolledover'efdge portion 21' immune track reaches a position relative to the 'rolled-over edge 21 where the slot 3 2 is" equal to io'r greater than the diammeter of the felt covered rolled over edge 21 thus causing Ithe tracki28'lto be disengaged from the attaching plate 18/ From the above description it is obvious that the attachment between the window and the window regulator permitsthe window tobe free- 1y .rotat'abl'e in' and out, that is, as viewed in Figures 2, ,3 and 6, the window 3 is not only free within limits'to swing inwardly or the body a counter-clockwise direction but likewise outwardly in a. clockwise direction about the felt surfac drubmar'p rtiqn 21' of thejplatewl8 as ahaxisl- The extentof this swing as the'windo'w is raised or lowered, of course, is determined by the relative position of the guide channels 11 and regulator. Because-the window isfree to fulcrum about the rolled-over edge 21 of the attaching plate 18, the travel of the window panel 3 in a plane not parallel or somewhat inclined to the plane in which the regulator arms and attaching plate 18 travel in their up and down movement will prevent any binding between the.

r panel, guides for the said panel, and a regulator window panel and the regulator.

When it is desired to disconnect. the window from the regulator one need only lower the window, remove the garnishmoulding 9 and.

channel guide 11, then raise the same. At this time the window may be tilted inwardly of the car, after raising the same slightly above the,

normal raised position, until the slot 32 of the track 28 rotates to a position about the felt covered rolled edge 21 where the slot 32.is equal to or greater than the diameter of this rolled edge,

of the plate 18 (Figure 6) whereupon the window can be withdrawn from the opening. It will be noted that with this type of roll-in attachment there is no need to remove the lock board 39 or the trim upholstery to permit installation or removal of the window panel.

It will be noted from Figure 1 that as the plate 7 18 travels back and forth in the track 28 as the window is raised and lowered, the center of the lower edge of the window panel 3 will always be some place between the ends of the tubular portion 21 of the plate 18. In other words, the tubular portion 21 of the plate 18 provides a multiple point suspension for the window and in all positions of the window supports the same on both sides of the center of its bottom edge thus preventing the window from cocking in its guides 4 and 5.
